| Influences of Track Transition on Track Vibration Due to the Abrupt Change of Track Rigidity |
| 摘要 |
| 建立軌道過渡段基礎(chǔ)剛度突變的軌道振動(dòng)微分方程，推導(dǎo)單輪作用下軌道變形的解析表達(dá)式。利用該解析解和疊加原理，研究軌道剛度突變對(duì)軌道振動(dòng)的影響，分析單輪對(duì)和TGV高速列車在3種軌道剛度比時(shí)的軌道動(dòng)力響應(yīng)。結(jié)果表明，軌道剛度突變對(duì)軌道振動(dòng)影響較大，軌道動(dòng)力響應(yīng)隨著 |
